Lucy of Syracuse is the saint depicted in the drawings you remember. She is indeed represented in art holding a plate with eyes on it. The following link shows one such painting, and further down on the page “eyes on a dish” is listed as part of her symbolism.

Lucy is one of several patron saints of the blind. Two of the other saints mentioned by the other posters in this thread, Saint
Dunstan and Saint
Odilia, are also on the list. Here is the link:
